Update GCC warning flags and function attributes to GCC 4.7.

* Makefile (WARN): Update to include almost all warning flags.
* plugin-runner.c (getplugin, add_to_char_array, add_argument,
                   add_environment, set_cloexec_flag,
                   print_out_password): Add attribute
                                        "warn_unused_result".
  (main/parse_opt): Bug fix: Add error checking to --global-env,
                    --env-for, --plugin-dir, and --config-file, and
                    make sure errno does not "leak" from unrelated
                    functions.
* plugins.d/mandos-client.c
  (fprintf_plus, debuggnutls, resolve_callback): Add "nonnull"
                                                 attribute.
  (incbuffer, add_server, init_gpgme): Add "nonnull" and
                                       "warn_unused_result"
                                       attributes.
  (pgp_packet_decrypt, init_gnutls_global): - '' -
  (init_gnutls_session start_mandos_communication, get_flags): - '' -
  (good_flags, good_interface, interface_is_up): - '' -
  (interface_is_running, runnable_hook): - '' -
  (avahi_loop_with_timeout, bring_up_interface): : - '' -
  (safer_gnutls_strerror): Add "warn_unused_result" attribute.
  (notdotentries): Set "nonnull", "pure", and "warn_unused_result"
                   attributes.
  (raise_privileges, raise_privileges_permanently, lower_privileges,
  lower_privileges_permanently): Set "warn_unused_result" attribute.
  (run_network_hooks): Exit child process if it fails to do anything
                       it needs to do.  Make explicit cast to double
                       when passing float value to asprintf().  Change
                       return type to void - all callers changed.
  (bring_up_interface): Move variables "sd", "ret_errno", and
                        "ret_setflags" to innermost scope.  Bug fix:
                        Fail if could not get interface flags also in
                        non-debug mode, and restore old errno
                        correctly.  Print message if could not raise
                        (or later lower) privileges.
  (take_down_interface): Bug fix: When failing because it could not
                         get interface flags, restore old errno
                         correctly.  Print message if it could not
                         raise (or later lower) privileges.
  (main): Complain if failed to raise or lower privileges.  Only run
          network hooks or lower privileges if raising privileges was
          successful.
